Abstract
Abstract A pie board having a disc provided with upper and lower, substantially parallel surfaces and a peripheral edge surface about which is arranged a clamping device for securing to the disc a flexible sheet disposed covering the upper surface of the disc. Suction cups, and the like, are mounted on the lower surface of the disc for permitting the disc to be adhered to a suitable surface supporting the pie board.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
250 words
A pie board comprising, in combination, a circular board having a substantially planar upper surface bounded by and extending fully between a continuous cylindrical outer peripheral edge, said board including a lower surface substantially paralleling said upper surface, a plurality of anti-slip depending support members support from said lower surface in widely horizontally spaced relation for supporting said board in spaced relation above a work surface upon which said support members rest, a flexible sheet overlying said upper surface and of a plan area, sufficiently greater than the plan area of said board and partially dependent on the effective heighth of said depending support members and the thickness of said board, to enable the marginal portions of said sheet all to extend downwardly over and below said peripheral edge and the lower surface of said board to a level appreciably below the lower extremities of said support members for defining a peripheral apron about said board over said work surface when said support members are supported therefrom, a resilient split cylindrical clamp band having adjacent opposite ends and snugly positionable about said board over the portion of said sheet extending downwardly over said peripheral edge and with the upper edge of said band substantially flush with the upper surface of the portion of said sheet disposed over said planar upper surface, and latch means operably connecting said opposite ends of said band for clamping said band over the portions of said sheet disposed over the peripheral edge of said board.
Claim 2
Dependent Claim
250 words
A pie board comprising, in combination, a circular board having a substantially planar upper surface bounded by and extending fully between a continuous cylindrical outer peripheral edge, said board including a lower surface substantially paralleling said upper surface, a plurality of anti-slip depending support members support from said lower surface in widely horizontally spaced relation for supporting said board in spaced relation above a work surface upon which said support members rest, a flexible sheet overlying said upper surface and of a plan area, sufficiently greater than the plan area of said board and partially dependent on the effective heighth of said depending support members and the thickness of said board, to enable the marginal portions of said sheet all to extend downwardly over and below said peripheral edge and the lower surface of said board to a level appreciably below the lower extremities of said support members for defining a peripheral apron about said board over said work surface when said support members are supported therefrom, a resilient split cylindrical clamp band having adjacent opposite ends and snugly positionable about said board over the portion of said sheet extending downwardly over said peripheral edge and with the upper edge of said band substantially flush with the upper surface of the portion of said sheet disposed over said planar upper surface, and latch means operably connecting said opposite ends of said band for clamping said band over the portions of said sheet disposed over the peripheral edge of said board.
Claim 3
Dependent Claim
38 words
A structure as defined in claim 1, wherein said support member comprises a plurality of suction cup assemblies mounted on the lower surface for adhering to a support surface and releasably affixing the board to the support surface.
Claim 4
Dependent Claim
68 words
A structure as defined in claim 2, wherein each suction cup assembly includes a suction cup provided with a central aperture, a screw arranged in the central aperture, and a knurled cap nut fitted in an associated hole provided in the board and threadingly engaging the screw for retaining the suction cup on the board, the suction cup having a gripping portion arranged diverging away from the board.
